On Security of XTR Public Key Cryptosystems Against Side Channel Attacks
The XTR public key system was introduced at Crypto 2000. Application of XTR in cryptographic protocols leads to substantial savings both in communication and computational overhead without compromising security. It is regarded that XTR is suitable for a variety of environments, including low-end smart cards, and XTR is the excellent alternative to either RSA or ECC. In [LV00a,SL01], authors remarked that XTR single exponentiation (XTR-SE) is less susceptible than usual exponentiation routines to environmental attacks such as timing attacks and Differential Power Analysis (DPA). In this paper, however, we investigate the security of side channel attack (SCA) on XTR. This paper shows that XTR-SE is immune against simple power analysis (SPA) under assumption that the order of the computation of XTR-SE is carefully considered. However we show that XTR-SE is vulnerable to Data-bit DPA (DDPA)[Cor99], Address-bit DPA (ADPA)[IIT02], and doubling attack [FV03]. Moreover, we propose two counter...
